Laser Spectroscopy Advanced Labs

 

 

 

 

Home

Experiments in the Laser Spectroscopy Advanced Labs are considerably different from those in introductory physics laboratory courses. These labs are using unique laser and spectroscopic facilities. It gives students introduction to the experimental research in the Laser Spectroscopy. Some of the advanced labs are structured, while others are based on current research projects. The advantage of the last is that overcoming of these Labs can lead to publications in the scientific journals and participations in International Conferences. Below one can find publication list where some experiments made by undergraduate students in the Laser Lab were a part of the scientific research; and where Advanced Labs were accomplished with publications. However, usually a preparation of the publication requires student’s dedications to the research and longer time that one term.

 

Fall 2021

This project proposes to find the simple conversion process from available laser wavelengths to get the specific excitation wavelength. The conversion rules are simple and include only arithmetic operations.  Despite this simple formulation, the outcome could be important for laser sensing applications, and it also includes the possible submission of patent application. All students who would like to discuss or solve this puzzle are welcome.

 

 

Advanced Labs in the Laser Laboratory include the following facilities

·         Sample Preparation (Cutting and Polishing)

·         Absorption spectroscopy

·         Fluorescence spectroscopy

·         Fluorescence Kinetics Measurements

·         Spectroscopic Characterization an Low Temperatures

·         Non linear laser spectroscopy

·         Raman and Micro-Raman Spectroscopy

·         Atomic Force Microscope

 

 

Using links below one can find presentations in the Adobe Portable Document Format(PDF) about several spectroscopic experiments with short summary of the standard experimental procedure used in the Laser Labs.
